Rock (geology) A naturally occurring solid aggregate of one or more minerals or mineraloids

Rock or stone is a natural substance, a solid aggregate of one or more minerals or mineraloids. For example, granite, a common rock, is a combination of the minerals quartz, feldspar and biotite. The Earth's outer solid layer, the lithosphere, is made of rock.

Its practice can be traced back to rock climbers in the 18th century in North America. [1]

Rock climbing sport in which participants climb up, down or across natural rock formations or artificial rock walls

Rock climbing is an activity in which participants climb up, down or across natural rock formations or artificial rock walls. The goal is to reach the summit of a formation or the endpoint of a usually pre-defined route without falling. Professional rock climbing competitions have the objectives of either completing the route in the quickest possible time or attaining the farthest point on an increasingly difficult route.

More specifically, "Boulder Trundling may be defined as the propulsion of fragments of the Earth's crust down mountain slopes of suitable inclination sooner than would occur from the interaction of natural forces." [2]

Bouldering rock climbing performed on small rock formations or artificial rock walls (<6 m tall) without ropes or harnesses; originated as a training method for roped climbs

Bouldering is a form of rock climbing that is performed on small rock formations or artificial rock walls, known as boulders, without the use of ropes or harnesses. While it can be done without any equipment, most climbers use climbing shoes to help secure footholds, chalk to keep their hands dry and provide a firmer grip, and bouldering mats to prevent injuries from falls. Unlike free solo climbing, which is also performed without ropes, bouldering problems are usually less than 6 meters tall. Traverses, which are a form of boulder problem, require the climber to climb horizontally from one end to another. Artificial climbing walls allow boulderers to train indoors in areas without natural boulders. In addition, Bouldering competitions take place in both indoor and outdoor settings.

Dry stone construction method

Dry stone, sometimes called drystack or, in Scotland, drystane, is a building method by which structures are constructed from stones without any mortar to bind them together. Dry stone structures are stable because of their unique construction method, which is characterized by the presence of a load-bearing façade of carefully selected interlocking stones.

Free climbing

Free climbing is a form of rock climbing in which the climber may use climbing equipment such as ropes and other means of climbing protection, but only to protect against injury during falls and not to assist progress. The climber makes progress by using physical ability to move over the rock via handholds and footholds. Free climbing more specifically may include solo climbing, traditional climbing, sport climbing and bouldering.
